GARBURETER.

Specification of Letters Iatent.

Patented Aug. 4, 1914.

Application filed April 10, 1912. Serial No. 689,821.

To all whom it may concern:

also in devices for mixing the required air therewithgand commingling the gases as they pass to the ignition chamber.

These l'eSUltSl are accomplished by the utilization of certain novel features of con struction and combinations of parts as illustrated in the accompanying drawings wherein I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles, and the device herein exemplified has proven highly satisfactory in actual practice.

Figure 1 is a sectional view of a carbu reter embodying the invention. Fig. 2 is a horizontal sectional view online 22 of Fig. 1. Fig. 3 is a horizontal sectional view on line 3-3 of Fig. 1, and Fig. 4 is a view of the throttle, detached.

In the preferred embodiment of the invention as herein illustrated the fuel is contained in the float chamber 1, as usual, the

standard float 2, valve 3, and inlet *1, for

fuel, being illustrated. The casing 5 which incloses the float chamber is provided with a central, conical tubular wall 6, open at the top, and communicating at its lower open end with an open chamber in the cy indrical extension 7. in. inlet mouth 8 communicates with the chamber within the extension 7, for the admission of hot air, as usual.

The cylindrical upper structure 9 of the carburetor is cylindrical in cross section and provides a hot water or air space 10. An inlet and outlet are indicated by the numerals 11 and the space may be supplied with either of the elements therethrough. The cylinder 9 is also provided with in inclcsed wall 12, which forms a passage way or duct communicating with and forming a continuation of the conical shaped passage within the tubular wall 6 of the float chamber. This wall 12, as seen in Fig. l is corrugated, as at 13, to form ducts or elongated chambers in the fuel passage to aid in comminaling the gases as they arise. And a further comminglingof the gases is produced by the novel form of throttle valve llwhich isprovidcd with pins 15 projecting therethrough and at each side thereof. The jacket 9 is provided with the usual air intake 16 and valve 17, and as these parts of the device are old and well known an extended description unnecessary.

The vaporizer 'ieludes a needle valve 18 integral with the stem 1!), which threaded at 20 into-a sleeve 21 that is in turn threaded into the bottom wall of the extension 7, and a clamp nut 22 hrlds the extension 7 in posi- ,tion. At its lmver end the stem is provided serted for turning the stem in the threaded sleeve to adjust the valve 18 in relation to its eat 24 formed at the upper end of the nozzle 25. A packing nut 26 closes the lower end of the sleeve 21 and is threaded thereon.

It will be seen that an ample space is provided within the nozzle for fuel which is fed thereto from the fuel chamber through duct or passage 26 which leads to a horizontal passage 27 passing through the supporting lug 28 of the mizzle support 29. (See Fig. 2.) In ad tion to the vaporizing or spraying device formed between the needle valve 18 and the contracted end 24. of the and is vaporized by the flew of hot air drawn in through the opening 8 and up through the conical tube (3. An additional jet of hydrocarbon is passed through the chambered extension of the 'alve, and at this point the \"apocreccivcs the additional supply of air through the auxiliary valve 17. As the gases for combustion pass upwardly through the pipe 12, they are broken up and commingled by passing through the ducts formed by the corrugatedv'all of the pipe, and a further separation and commingling is occasioned by the rods or pins 15 in the throttle 14. In this manner a'thoroughly mixed fuel is supplied. to the manifold of the engine.

From the above description taken in connection with the drawings it is believed the merits of-my invention will be apparent, and

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is I. In a carburetor, the combination with a nozzle having a contracted mouth and a fuel suprdv, of a stem formed with a needle-valve to CgyaCt with said contracted mouth, and an extension on the end of said valve having a passage therethrough communicating with the interior of the nozzle and forming an r. additional vaporizing jet.

in a carburetor, the combination with a nozzle having a contracted mouth and fuel supply, a threaded stationary sleeve forming.

a continuation oi the nozzle and means for securir the sleeve in the carbureter, of a stem th .zul ed into said sleeve and provided with a needle valve, and an extension on said valve having a passage therein comnnrnicatingzj with the interior out the nozzle and Forming a vaporizing tlopies c having a passage therethrough communicating with theinterior of the nozzle and forming an additional vaporizing jet.

4. In a carbureter, the combination of a. reservoir, :1 cover on the reservoir having a mixing tube extending transversely thereon and an air-inlet tube extending from the mixing tube through the reservoir, and a fuel feed tube connected with the reservoir and having a nozzle supported in the airiulet tube to discharge therein toward the mixing tube, with dual means in the air-inlet tube for controlling the discharge from thenozzle, one of the means being adjustable for rapacity and the other relatively smaller and constant in capacity.

.lntestiinony whereof I aliix my signature in presence of two Witnesses.
